Spacecraft on the approach to asteroid will slingshot past Earth on Friday

NASA’s OSIRIS-REx spacecraft, on a lapse goal to a far-off asteroid Bennu, will pass by Earth on Friday, and you’re invited to call as it goes by.

OSIRIS-REx — that has been orbiting a object for a year — is on a seven-year mission to a asteroid, that lies more than 322,000 kilometres from Earth. While a booster is scheduled to arrive there in Aug 2018, it contingency bear some manoeuvres to adjust a arena but regulating fuel, one of that is a gravity-assist.

The booster will use Earth’s sobriety to slingshot toward a asteroid. This is fourth arena improvement engineers have done to OSIRIS-REx.

On Friday, a booster will fly only 17,000 kilometres above Earth during about 12:52 p.m. ET,  between Antarctica and Cape Horne. OSIRIS-REx has already trafficked 965 million kilometres.

To regulate a instruments, 4 hours after a tighten pass by Earth, OSIRIS-REx will make systematic observations of Earth and a moon.

Look adult and wave

NASA and a goal partners are seeking a open to attend in a Wave to OSIRIS-REx social media event by taking photos of themselves waving. They can post a cinema on Twitter regulating a hashtag #HelloOSIRISREx. 

Canada has contributed a critical square of orchestration to a mission, called a OSIRIS-REx Laser Altimeter, which will glow a laser and emanate a 3D map of a asteroid. It will be a many minute map of an asteroid and yield scientists with information on a asteroid’s shape, rocks and topography.

This is a singular mission: aside from mapping Bennu, OSIRIS-REX will also collect samples from a asteroid and broach them behind to Earth, a initial for NASA.

Bennu was selected in partial for a relations vicinity to Earth. It is also famous as a carbonaceous asteroid, one that is carbon-rich and that has altered really small given a birth of a solar complement 4.5 billion years ago. It’s believed that asteroids like it could enclose organic molecules and amino acids, some of a building blocks of life.

OSIRIS-REx will lapse to Earth on Sept. 30, 2025.
